How do Hitachi’s heat pumps save me energy and money?
Hitachi’s�air�source�heat�pumps�–�Yutaki�and�AquaFREE�-�work�
by�transforming�energy�from�outside�air�into�heat.��
Put�simply,�every�1�kilowatt�of�electricity�used�to�power�the�
heat�pump�is�capable�of�providing�up�to�4�kilowatts�of�energy�
in�a�well-insulated�home�–�helping�to�reduce�heating�bills.
The�heat�pumps�are�controlled�by�energy-saving�weather-
compensation�sensors�that�adjust�according�to�the�difference�
between�inside�and�outside�temperatures.�
And�because�Hitachi�heat�pumps�require�significantly�less�fossil�
fuels�(such�as�gas�and�oil)�to�operate,�they�allow�homeowners�
to�save�up�to�60%�on�running�costs.�

Are they easy to install?
Yes�–�in�both�modernisation�projects�and�as�new�installations.
Hitachi�heat�pumps�can�be�connected�to�all�common�radiators,�
underfloor�heating�systems,�convectors�and�water�heaters�–�tailored�
to�your�requirements.
Can I make long-term savings?
Because�Hitachi�heat�pumps�are�capable�of�reducing�CO2�emissions�
by�50%�compared�to�a�boiler-led�system,�this�makes�them�a�worth-
while�long-term�investment.�
And�with�fewer�moving�parts�to�go�wrong,�the�heat�pumps�have�a�
long�life�expectancy.�They�also�increase�the�value�of�homes�and�give�
you�access�to�government�grants�and�funding.
1�kW�Consumption�=�4�kW�Heat�outputThis�is�on�average�more�than�60�%�free�energy!
How does the heat pump actually work?
Air�source�heat�pumps�use�a�refrigeration�process�to�transfer�low-grade�
energy�from�the�outside�air�into�high-grade�energy,�perfect�for�heating�
and�domestic�hot�water.�Even�at�temperatures�as�low�as�-20°C,�the�
heat�pump�can�supply�significantly�more�energy�than�it�uses.��
The�AquaFREE�can�also�reverse�this�procedure.�During�the�summer,��
it�can�reduce�the�temperature�of�rooms�by�withdrawing�heat�and�
releasing�it�outside�via�an�outdoor�unit.��
During�winter,�heat�energy�is�transferred�from�outside�to�inside�a�home.
In�summer,��heat�energy�is�released�from�inside�to�outside��(only�possible�with�AquaFree).
What features make Hitachi heat pumps so energy efficient?
Hitachi is one of the first manufacturers to use cutting-edge
DC Inverter Technology.
This�keeps�temperature�fluctuations�to�a�minimum,�giving�customers�
the�opportunity�to�tailor�the�temperature�of�their�homes�to�their�own�
preference,�whilst�saving�up�to�40%�of�energy�compared�to�systems�
without�this�technology.
Which Hitachi heat pump do I need?
This�decision�depends�on�many�factors,�including�the�size�of�your��
flat�or�house,�the�type�and�number�of�heating�elements�involved�and�
warm�water�function.�Your�living�environment�also�plays�an�important�
role.�In�general,�you�can�use�both�Yutaki�and�AquaFREE�in�connection�
with�common�radiators�or�underfloor�heating�systems.
The AquaFREE heat pump is a split system,�consisting�of�an�
outdoor�unit�and�a�separate�indoor�unit.�It�can�be�fitted�with�auxiliary�
heating,�but�requires�additional�space�inside�your�home.�The�
AquaFREE�pump�is�extremely�quiet�and�highly�efficient.
In contrast, the Yutaki heat pump is a compact solution,�
whereby�only�a�single�unit�has�to�be�installed�on�the�outside.�It�does�
not�take�up�much�space�and�can�use�an�existing�heating�solution.
Your�Hitachi�specialist�dealer�will�be�happy�to�help�you�make�the��
right�decision.

- Heating and cooling possible
- Available with and without out electric auxiliary heating
- Split system: outdoor and indoor unit only available as a set
The�AquaFREE�split�indoor�and�outdoor�unit�uses�simple�principles�of�
thermodynamics�to�move�heat�from�one�place�to�another.�It�absorbs�
heat�from�the�air�outside�and�transfers�it�to�the�internal�unit,�which�in�
turn�transfers�the�absorbed�heat�to�the�water�circuit.
The�water�circuit�–�which�is�controlled�by�the�system�-�can�determine�
and�adjust�heating�requirements�depending�on�outdoor�temperature.�
So�if�it�is�hot�outside,�flow�temperature�will�be�reduced�–�saving�the�
homeowner�unnecessary�energy�waste�and�lowering�heating�bills.��
The�flow�temperature�reaches�values�from�18�to�48°C.�By�also�fitting�
an�optional�evaporation�tray,�it�is�even�possible�to�reach�temperatures�
of�up�to�7°C�in�cooling�mode.�

1 Rated refrigeration resp. heat output at temperatures in accordance with the respective column (without electro auxiliary heating), Tube length 7.5m, Height difference 0m.2 The cooling mode is not an option with radiators (condensed water formation). Only possible with fan convectors with condensation water tray. In addition, an evaporation tray has to be fitted at the indoor device (AF-DPK-WH).3 Sound pressure level measured at a distance of 1.5m (measured in a completely soundproof room without reflections).4 A separate control (AF-BCK-01) is available for the combined operation with conventional heating systems. Cooling with fan convectors requires the installation of a condensation water tray (Standard: AF-DPK-NH, with electro auxiliary heating: AF-DPK-WH).
